  • the protective circuit part typically includes a protective circuit board in which various devices are mounted on a printed circuit board (PCB), and is electrically connected to a cell through a conductor referred to as a connection tab.
  • PCB printed circuit board
  • a defect may be caused if the iron contacts the protective circuit part.

  • the first and second covers may be integrally formed.
  • the opening part may include a hole formed through the second cover.
  • the opening part may include a recess at a side of the second cover with respect to the protective circuit part.
  • the apparatus may further include a position setting part on the cell or the protective circuit part for setting a position of the cap.
  • the position setting part may include a first extension part extending from a side of the first cover opposite the second cover and configured to surround the cell; and a second extension part extending from a side of the second cover opposite the first cover and configured to surround the protective circuit part.
  • a method of manufacturing a core pack including a cell and a protective circuit part using a core pack manufacturing apparatus including a cap including: covering the cell with a first cover of the cap; covering the protective circuit part with a second cover of the cap extending from a side of the first cover; and soldering a connection tab connected to the cell to a connection terminal of the protective circuit part through an opening part of the second cover.
  • the method may further include locating a side surface of the cap using a line or a point marked on the cell.
  • the method may further include surrounding the cell with a first extension part of the core pack manufacturing apparatus extending from a side of the first cover opposite the second cover; and surrounding the protective circuit part with a second extension part of the core pack manufacturing apparatus extending from a side of the second cover opposite the first cover.
